A student wanted to check her idea that a planet that is closer to the Sun receives more of the Sun’s energy than a planet that is farther away from the Sun. She placed a radiometer 50 cm
away from a clamp light with a 150 –W lightbulb
To check her idea, she also needed to set up another clamp light and radiometer.
Which of the following setups would she use?
A. a clamp light with a 50-W lightbulb placed 25 cm from the radiometer
B. a clamp light with a 50-W lightbulb placed 50 cm from the radiometer
C. a clamp light with a 150-W lightbulb placed 25 cm from the radiometer
D. a clamp light with a 150-W lightbulb placed 50 cm from the radiometer
